DEVICE FOR OPERATING FANS ON ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent N 0. 682,467, datedSeptember 10, 1901. Application filed November 13, 1899. Serial No.736,730. (No model.)

To all whom it may concern.-

Be it known that I, GOTTLIEB A. HEIM- BUCHER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Devicesfor Operating Fans on Rocking-Chairs, of which the following is a full,clear, and exact specification.

My invention relates to that class of devices designed to be operated bythe natural rocking movement of a rocking-chair, whereby the occupantthereof may receive the benefit-of the fan without the expenditure ofextra effort or the exercise of special attention for its operation.

The primary object of my invention is to provide an improved and simpledevice whereby a fan may be kept in motion on a rocking-chair as long asthe occupant thereof rocks back and forth.

A further object of the invention is to make the device noiseless,easily adapted and adj usted to the chair, and adjustable to suitoccupants of various heights.

With these ends in View my invention consists in certain features ofnovelty in the construction, combination, and arrangement of parts bywhich the said objects and certain other objects hereinafter appearingare attained, all as fully described with reference to the accompanyingdrawings, and more par- 1 ticularly pointed out in the claims.

In the said drawings, Figure 1 is aside elevation of a rocking-chairwith my improvements applied thereto. Fig. 2 is a side elevation of thedevice on an enlarged scale, partly in vertical section and partlybroken away. Fig. 3 is a front elevation, partly in vertical section;and Fig. 4 is an enlarged detail vertical sectional view of thesupportingtube and operating-rod,hereinafter described, showing a doubleturnbuckle-joint for adj usting the two said parts simultaneously andincreasing or decreasing their length.

I have shown my invention as applied to that type of rocking-chair inwhich a base portion is provided for the chair to rock on; but it willnevertheless be understood that my invention is not limited to thisparticular style of chair.

1 represents the base of the chair, and 2 the rocking-chair supportedthereon. To the under side of the bottom of the rocking-chair I secure aboard 3, which projects slightly from the side of the chair and forms abracket or ledge for the support of a drum or pulley 4, mounted upon ashaft 5 in suitable standards 6, which are secured by screws 7 or othersuitable devices to the upperside of the projecting end of the board 3.Around this drum or pulley 4 is taken one or more turns of a cable orcord 8, whose lower end is attached by means of lug or bracket 9 to arod 10, while its upper end is also secured in any convenientway to theupper end of such rod. The lower end of this rod 10 is connected byhinge-joint 11 to the base 1 of the chair, so that when the chair rocksback and forth the cord or cable 8 will be compelled to remain at restwith the rod 10 and as a consequence impart a rotary motion to thepulley or drum 4 and its shaft 5. 'In order to properly support the rod10 with relation to the drum 4, I sleeve upon the shaft 5 a collar 12,which oscillates around the pulley 4, concentrically therewith, andthrough which collar 12 passes the rod 10, thus holding the rod at auniform distance from the periphery of the drum or pulley at all times,while permitting the pulley to go and come with the rocking movement ofthe chair. In order that the slack of the cord or cable 10 may at alltimes be taken up automatically, I prefer to attach its upper end bymeans of a yielding connection, preferably consisting of a threaded rod13, passing through an adjustable bracket 14 on the upper end of the rod10 and having a spiral or other suitable spring or cushion 15 sleevedthereon between the bracket 14 and an adjustable nut 16, the tendency ofthe spring 15 being to pull the rod 13 through the bracket 14, and thuskeep the cable 8 taut. By this means it will be seen that I provide avery simple and efficient device for imparting a to-and-fro rotarymovement to the drum 4 and its shaft 5 and a device which at the sametime is noiseless and does not require the presence of grease or oil,which in some cases might be objectionable.

The outer end of the shaft 5 is provided with a crank 17, which isconnected bya pitman 18 to a sliding cross-head 19, arranged in thelower end of a tubular guide 20, which also serves as a support for thefan 21. The fan 21 is provided with a stem or handle 22, preferablyformed of a channel-bar, as shown in Fig. 2, and provided with a seriesof perforations 23, through one of which passes a pin 24, which securesthe stem 22 to the upper end of an operating-rod 25, whose lower end hasa piston or head 26 secured in an elastic packing 27, contained in achamber in the cross-head 19, such chamber being closed by ascrew-cap28, thus forming a yielding connection between the cross-head and the.

rod 25. As the shaft 5 rotates the cross-head 19 will impart arising-and-falling movement to the rod 25 and as a consequence avibratory movement to the fan 21. The stem of the fan is supported by apair of pivoted links 29, whose upper ends are connected by pin 30 tothe stem of the fan, While their lower ends are pivoted, by means ofscrews orother devices 31, to a collar 32, sleeved onthe upper end ofthe tube 20, the collar being held by a set-screw 33, whereby it may beadjusted up and down to vary the inclination of the fan or rotate it tochange its position with relation to the sitter. In order that theelevation of the fan may be varied to suit the height of the sitter, Iprovide the rod 25 and the tube 20 each with a turnbuckle, as moreclearly shown in Fig. 4. The turnbuckle of the tube 20 consists of asleeve 34, threaded at both ends to upper and lower sections of the tube20 and having an internal web 35, in which is loosely arranged a squaredportion 36 of a sleeve 37, which is threaded at both ends to upper andlower sections of the rod 25, so that by rotating the sleeve 34 the samerotation will be imparted to the inner sleeve 37, and as the sleeves arethreaded right and left at oppositeends and at the same pitch it followsthat the rotation of the outer sleeve will adjust the length of the rod25 and tube 20 equally.

I prefer to sleeve upon the upper end of the rod 25 a coil-spring 38,which bears against the pin 24 and upon the upper end of a guide 39,formed on or secured to the upper end of the tube 20, so as to balancethe mechanism.

tion, because the same constitute the subject matter of the claims in mypending application, Serial No. 727,640%,-fi1ed August 18, 1899.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is.-

1. In a device for the purpose described the combination of arocking-chair, a fan, a tubular support for said fan secured to saidrock ing-chair and comprising two sections and a threaded sleeveconnecting said sections together, a rod arranged in said tubularsupport, connected with said fan and comprising two sections threaded attheir contiguous ends, a portion threaded to each of said sections andarranged concentrically in and having operative connection with saidsleeve whereby the rotation of said sleeve will also rotate the lastsaid threaded portion, and means operatively connected with said rod foroscillating the fan by the rocking move-' ment of the chair,substantially as set forth.

2. In a device for the purpose described the combination of arocking-chair, a fan, a tubular support for said fan on saidrocking-chair, comprisingtwo sections ad justably connected together, anoperating-rod arranged in said tubular support and comprising twosections also adj ustably secured together, means for adjusting saidtubular sections and means for adjusting said rod-sections operativelyconnected with said first means whereby the same will be actuated toadjust the tubular sections and rod sections simultaneously, means forconnecting the fan with one of said rod-sections and means forreciprocating said rod-sections by the rocking movement of the chair,substantially as set forth.

3. In a device for the purpose described the combination of arocking-chair, a fan, a tubular support for said fan upon said chaircomprising two sections threaded at their contiguous ends, a sleevethreaded on said contiguous ends of said support and having an internalweb provided with a squared aperture, a rod connected with said fan andcomprising two sections threaded at their contiguous ends and arrangedin said support, a member having a squared exterior passing through thesquared aperture of said web and threaded at opposite ends to saidrodsections respectively and means for oscillating said rod-sections bythe rocking movement of the chair, substantially as set forth.
